slowing down from highway speed at the one corner i have to make to get into town i loose power boost and my brake petal goes rock hard. its done this once or twice briefly before(usually a brief off-throttle will bring it back) but this time it stayed unpowered the rest of the three miles into town. then, rolling up to the first light off throttle...i get full boost back and brakes operate normally. been fine all day today as well. thoughts? i did trigger abs on a few icy spots before i got on the highway. aaand was just reading about the abs recall. could this be related? i cant find any service records in my stack about the former owners replacing that module.
